bodies, due to the inclination of the chute,

are disposed to roll to the delivery end of the chute under the influence of gravity at which point they are received by the ini'grmittently rotating turret 23, as shown in ig. 6. a

The can caps, designated generally by reference character 24, are contained'in a magazine of suitable construction mounted adjacent thechute 19. This magazine, as best shownin Figs. 1 and 10 to 15 inclusive, comprises a plurality of vertical guide-rods 2 5 supportedin sockets 26 having horizontally disposed portions 27 slidably mounted in guideways 28 formed uponthe upper end of a supporting bracket 29. The sockets are adjustably supported on the guideways bybolts 31 engaged in slots 32 (Fig. 2). so that the guide-rods may be adjusted closer together or farther apart to' accommodate can The base 33 of the magazine is annular'in shape and provided with a plurality of, preferably four, radially disposed guideways or slots 34 adapted to receive and guide in their longitudinal movements cap supporting fingers 35, 36, 37

and 38 respectively. Each finger is provided with an upwardly projecting pin 39 engag ing in an inclined slot-formed in an oscil-Q latory ring 41 overlying the fingers and guided in its movements by a cap-shaped.

member 42.- It will be observed that slots 43 and 44, with which the pins of fingers 36 and 38 respectively engage, are inclined oppositely to 'the slots '45 and 46, with which the pins of fingers 37 and 35 respectively engage, with the result that when the ring 41 is rotated in" one direction the pair of fingers 35 and 37 will be withdrawn from comprising fingers'36 and 38, will be proected into the path of the caps while upon each pair will be movedin the opposite d.i-' rection. This result will be best understood from an inspection of Figs. 12 to 15 in- In Figs. 12 and 13 the fingers 36 and 38 are disposed beneath the lowermost fingers 35 and 37 are withdrawn, as shown oscillation of the ring 41 Fig. 12,v fingers 35 and 37 will be inserted above the lowermost and beneath theremainder of the caps while fingers 36 and 38 will be withdrawn to release the'lowermost cap, permitting it to drop from the bottom of the magazine while the remainder of the stack is supported by fingers 35 and 37, as

shown in Fig. 15. Upon oscillation of the ring 41 in a clockwise direction, viewing Fig. 12, fingers 36 and 38 will be projected into the position shown in Fig. 13 while fingers 35 and 37 will be withdrawn into the position shown in Fig. 14. Itwill, be mani- .at predetermined intervals from simultaneously with the can bodies.

fest that the caps are released in succession the mega zine by oscillation of the ring 41.

The rin 41 is oscillated by means of a continuous y rotating vertically disposed shaft 47 mounted in suitable bearings on the bracket 29, provided at its upper end with a cap 48 loosely mounted thereon and carry ing a crank pin 51 which is connected by a "pitman or link 52 with a pin 53 secured to the ring 41 and projecting downwardly through a slot formed in the base plate 33. riving connection is established between the shaft 47 and cap 48 by a clutch member 55 splined'on the shaft 47 and adapted to engage with a clutch face on the cap 48. The clutch member 55 is controlled. from a bell crank lever- 56 pivoted on the bracket: 29 at 57 and adapted to be held by a pivoted spring controlled latch 58 to maintain the clutch in either closed or open position. This clutch orthrow-out mechanism is provided so that the feeding of the caps may be stopped when desired without stopping the whole machine.

When the caps drop from the magazine they fall upon an inclined plate or guideway 59 shaped to turn the caps from a horizontal into a vertical position so that they will enter the'guide-groove 61- adjacent one side of the chute 19 and will roll down this inclined guide-groove. parallel with the can bodies and will be delivered to the turret 23 11 other words, the cap releasing mechanism is timed with respect to the turret so that a cap is released and delivered to the turret each time an' empty turret socket is brought int'oa'linement with-the chutes 19 and 61.

The shaft 47 -'is driven through the intermediary of beveled gears 62 from a cross shaft 63 driven by. means of a belt or chain 64 from a counter shaft 65. This counter shaft has a pair of large gears 66 and 67 ofequal size fixed thereon 'at opposite sides of the machine and the shaft is driven through gear 67 from a; pinion 68 clutched on the main-drive shaft 69 which in turn receives powerthrough a pulley 71 from any suitable source. A- manually operated clutch 72 of any well known for preferred construction is preferably employed to establish connection between the drive pulley cured upon 5 a turret shaft 74 mounted in suitable bearings at its ends on the main frame. The turret, as best shown in Fig. 9, comprises a body porti0n75 secured to the turret shaft by pins 76 or otherwise, and two end members '77 and 78 respectively adjustably keyed to the body bya key 7 9.

The end member 78- 'is provided with a se-- ries of radially arranged sockets 81: adapted to receive and Support one end of can '5 bodies 17, and member. 77 is provided with similar sockets 83 to receive and support the other end of the can bodies. Member 77 is also provided adjacent each body.

socket 83with a cap socket 84 -which, as willbe evident from Fig. '9, deeper than the 1 body socket so that-a can cap will be held in the cap socket substantially concentric with the can body carried ill-sockets 81 and '83. From' Fig. 2 it. will .be observed that the end members 77 and. 7 8' are so positioned that the sockets 81 and 83 he .in' .alinement with the. can body chute. 19 and the cap sockets 84 are alined withthe cap chute-61.

The can. bodies and capsf are' delivered,

the chutes 19 and,61, aswill be readily under'stood. In orderto'prevent the caps from v dropping out of the; cap socketslongitudi nally of the turretl have provided each 26 socket 84 at its base and at the outer endof qthe turret with a flange 85, as shown in Figs.

The chuck 107 substantially identical with the one just ascribed, and this chuck isalso equipped with a pinion 131 disposed in alinement with pinion 117. These pinions are both driver; as the same speed by a rotatably. mounted on the lashing with pinions 11'? and 1; A 133 integral with the or car meshes with and is driven by the ear '67 with the result that. the chucks 10B are continuously driven driving gear r through this chain of gears from the driving I shaft The icks and 111 are substantially iderrsicai in construction and a detailed .description of chuck which is shown in section in Figs. 53 and will sufice for an understanding of both The frame of the machine at side is shaped to provide a supporting portion 13& in which is mounted a reciprocatory block or housing 135 adapted to carryboth chucks 109 and 111. The block or housing is cored for each spindle to receives bushing 136 (Fig, 9) in which thechuck spindle 1 37 rotatably mounted.

A pinion 138 is'secureol to the spindle adjacent its nner and upon the inner end of the spindle is threaded a chuck head 139 shaped on its inner face to fit the can cap,

7 chuck 109 is provided with a pinion-1&3' and as shown in Fig An adjusting screw 1&1 abutting against a stud 1&2 provides an end thrust bearing i'or the spindle. The

pinions 1 58 and 1&2- both mesh with and are driven by a gear 1&& rotatably mounted on the turret shaft 7&, which gear in turn is driven from the gear 56 through the pinion 1&5 integral with the of gear 1&&. It will thus be manifest that all of the chucks are rotated at one the same speed and the same direction and that chucks 107 and 189 are dispcsedir. alinement at opposite ends of the turret to form the first pair between which the can bodies and caps will be positioned, and that chucks 108 and 111 are also mounted in alinement, forming the second pair of chucks between which the' bodies and caps are clamped after leaving the first pair.

The block or housing 135 is reciprocated longitudinally at predetermined intervals,

carrying the chucks 1G9 and 111 therewith,

macros by means of a bell crank lever pivoted bearings 1&6 on the adjacent side of'the ma: *chine and comprising an arm 1&7 ccnnecten at its upper end by links 1&8 to the housing and a downwardly projecting arm 1&9

its outer face, as shown in Fig. 3, surroundec by a shoulder 153, the margin of the cap being bent to form a flange 15 1. The chuck heads of the longitudinally movable chucks 109 and 111 are each formed on their inner faces hi: the caps and are provided with peripheral flanges 155 substantially equai in thickness to the depth of the cap shouiders 153, so when the heads are moved inwardly to clamp a can against its body the outer faces of the chuck head flanges lie substantially flush vvith'the outer faces of the flanges of the cap, as shown in Fig. "S1 The chuck heads 121 are preferably faced with a knurled steel plate or other similar means 15@ to present a non-slipping surface Y to the corresponding end of the can body;

The movement of the chucks 109 and 111 inwardly is sufiicient to firmly clamp the car.

bodies caps together and cause them to rotate with the chucks, and a firm clamping is insured by reason of the expansion 129 acting on the chuck head 121, which s ring also compensates for any difierences in the length of the can bodies.

Upon an upwardly extending portion 157 of the main frame at the rear of the machine is mounted a plurality of seaming tools which will now be described. Theprimary tool which preliminarily seams the can caps onto the bodies as they are rotated by the first pair of chucks 107 and 109 consists of a roller 158, best shown in Fig. 7, provided with peripheral'groov 159 which, as the -roier is'forced against the flange of the can cap, crimps the flange over onto the flange substantially as shown in Fig. 4'. A. central flange 161 adjacent the groove 159 is adapted to overliethc outer face of the can capomargin and also to overlie the outer face of the chuck head flange 155 so as to prevent the upward bending of the metal of the cap and insure the proper crimping action. A groove 162 similar in all respects to groove 159 is formed on the roller on the opposite side of flange 161 thereby rendering the tool capable of being reversed on its bearing pintle 163 so that its length of service is doubled. The tool is mounted between the forks of a reciprocatorybar 16& guided in a. bracket 165 and adjustably connected by means or" a; threaded connection 166 with a head comprising the two pieces 16? and 158 between which a piece of rubber 169 or other yielding "material is inserted 175- (F ig. 8) similar to the roller 158 but-- the peripheral groove 176 in this instance to permit a slight retractive movement of the tool when the longitudinal seam of the can passes thereunder; This yielding strip or member 169 enables thetool to beheld firmly against the work without exerting undue pressure, such as might break the tinfaround the longitudinal'fseam of the can body .when .thetool-engag'es therewith.
